Antidote

Keywords: Distributed computing - Distributed Data Management - Cloud storage - Large scale

Functional Description: Antidote is the flexible cloud database platform currently under development in the SyncFree and LightKone European projects. Antidote aims to be both a research platform for studying replication and consistency at the large scale, and an instrument for exploiting research results. The platform supports replication of CRDTs, in and between sharded (partitioned) data centres (DCs). The current stable version supports strong transactional consistency inside a DC, and causal transactional consistency between DCs. Ongoing research includes support for explicit consistency , for elastic version management, for adaptive replication, for partial replication, and for reconfigurable sharding.
